It may sound like a makeup faux pas, but Bettelli recommends starting with a foundation that's one to two shades darker than your complexion if you're going for a bronzed makeup look. "Mineralize Moisture ($33) is my favorite for the Spring/Summer season," she says. "It adds a radiant glow and sunscreen to your daily routine."

Helpful tip: Match your foundation to your arms, which usually get more sun and and are slightly darker than your face.
